Results of the implementation of a sensor network based on Arduino devices and multiplatform applications using the standard OPC UA

Abstract:

The Internet of Things is a technological paradigm that can be described as the set of elements that have small-embedded systems. This consisting of sensors, microprocessors, interconnection modules and actuators, which communicate with each other, to share useful information and improve processes. However, there are a large number of solutions from different vendors, both licensed and open source, that when deployed together may present problems, mainly due to a lack of standardization. In this paper we propose the use of OPC UA as middleware between MQTT and cross-platform Web applications. In addition, we develop a data management platform. Among the results obtained, it is possible to show the advantages of using MQTT and OPC UA, since it provides greater efficiency in the response time and security of the application.
